BN006:
Biogeochemical Processes Across Oxic-Anoxic Transitions


Session ID#: 28621

Session Description:
A suite of metabolically and chemically important oxidation-reduction reactions occur through the transitions from oxic to anoxic regions of the ocean. These reactions drive nutrient availability and metal solubility, as well as organic matter production, consumption, and preservation. As oxygen minimum and deficient zones expand, redox reactions in low to no oxygen environments are becoming globally more important, both for the nitrogen and carbon cycles and also for trace metals. Understanding such environments can provide an important analogue for ocean chemistry and microbial life in the Precambrian, prior to the great oxygenation events. This session seeks to bring together geochemical, biological, and physical scientists working on low oxygen and anoxic regions, in order to create an integrated picture of biogeochemistry in these environments. Presentations from observational, experimental, or modeling standpoints on nutrients, trace elements, dissolved gases, isotope systematics, microbiology, biological productivity, or physical drivers in these regions are all invited. We especially encourage submissions investigating the redox transition in the water column or sediments of restricted basins such as Saanich Inlet and the Black Sea, as well as GEOTRACES and open-ocean studies of settings such as the Eastern Tropical Pacific, North Atlantic, and Indian OMZs.
